Linux appimage prebuild aurora (#121)

* Linux Appimage: statically prebuild Aurora (and all its dependencies)

adds symlinks to the compiler locations in a static path that way rebuilds do not think that the compiler path has changed between appimage install commands

* Update package.yml

* Update Launcher/build-appimage.sh
